Here's to first aid for colds" Alka-Seltzer ad, Radio-TV Mirror February 1953
The pattern
This still is filed under Problem-agitate-solve.
Define
Name the problem, make the cost of leaving it felt, then present the way out as relief.
Mechanism
Tension then release. The offer is not an interruption. It is the only door once the cost of staying is clear.
Verdict
The problem is known but not yet urgent
Why it works
The demonstration does the selling: a fizzing glass in a real hand is the product already working, so the reader sees relief rather than reads about it. The symptom checklist is a self-qualifier, letting a reader tick their own cold and conclude the product is for them, and it disguises a claim as a specification. The red bottom strip performs the cross-sell, extending the purchase from a seasonal cold buy to a year-round one without stealing space from the cold argument.
Steal this when
Use this when your product treats a bundle of symptoms or complaints and the buyer only recognises one of them. Lead with the visible demonstration, then let a ticked list name the rest so the reader enlarges the problem themselves.
